SEAL FonV BOTTLES.

SPECIFICATION forming part of Letters Patent No. 574,672, dated January 5, 1897.

Application filed August l0, 1896. Serial No. 602,308. (No model.)

To all whom t may concern.: 'a Y Be it known that l, CHARLES WRIGHT DA- VISON, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Seals for Bottles, of which the following is a specification.

My invention relates to means for sealing bottles in a way to render it impossible to refill the bottles without such action being made evident to the purchaser.

The object of the invention is to provide a seal which may be readily applied to the bottle and which when once applied cannot be removed without breaking a portion of the seal.

The further object of the invention is to provide a cheap seal which may be quickly applied.

This invention consists generally in the combination, with the neck of the bottle, of a cap to thread thereon, said cap havingpa fragile top, and a suitable lock arranged between the sides of the neck and the cap.

The invention further consists in a cap provided with means forlockin g it upon the bottle-neck, having suitable trade-marks or otherl devices employed upon its fragile portion and corresponding to trade-marks or de vices upon the body of the bottle.

The invention will be more readily understood by reference to the accompanying drawings, in which- Figure l is a perspective'view of a bottlel provided with a seal embodying myinvention, showing the trade-marks applied upon the bottle and upon the seal. Fig. 2 is an enlarged perspective view of the neck of the bottle, showing the thread thereon and the metal splinter or lock. Fig. 3 is a sectional and perspective view of the cap or seal. Fig. 4 is a sectional view of the neck and the seal of the bottle. Fig. 5 is a perspective view of a modified form of the locking-piece.

As shown in the drawings, 2 represents a suitable bottle, the neck 3 of which is provided with a thread 4. This thread at the top is provided with a gap 5 to receive the splinter or look 6, which is preferably made of metal. Held in the gap the lock cannot lnove around the neck of the bottle. The lower end of the splinter or lock preferably rests upon the lower end of the thread 4. The cap '7 is circular. Its sides are preferably quite thick, while its top 8 is convex and quite thin. This top carries the impression or stamp or trademark 9. l

As the cap is preferably made of glass, terracotta, or like material, the trade mark is stamped or blown in the top thereof. Other material may be used for making the cap,sueh, for instance, as papier-mch or metal. If metal, the sides are made of heavier material than the top, so that the top may beeasily de stroyed. The cap is provided with an interior thread l0 to fit upon the neck of the bottle and in addition is provided with a narrow vertical recess ll. l

The lock or splinter G is provided with an outwardly-bent tongue or portion 12, and as the cap isscrewed down upon the neck this tonguerwill snap back into the recess il, when the same is turned opposite thereto. The lock is provided with the long and preferably thin upper end 13, and this end, as best shown in Fig. 1i, is adapted to curl down underneath the top of the cap. It will be seen that the cap thus locked in place cannot be turned in either direction, and the thread prevents its being pulled oft' the bottle. Access cannot be had to the lock from the under side of the cap, as the lower end of the thread closes the opening thereto. It is possible to remove the lock, therefore, only after breaking in the top of the cap, after which the end of the lock or splinter may grasped by a suitable tool and drawn out. The cap may then be easily unscrewed, after which the cork 14 of the bottle may be drawn.

In place of the splinter Ior lock shown in Fig. 2, the ends of which are sharp and might injure the hands of the person opening the bottle, I may employ the square-ended blank shown in Fig. 5. Where the thread 4 is made shorter than shown in FigQ, so that it does not project beneath the end of the lock, I provide for supporting the lock by striking a lug 16 from the lock. (Shown in Fig. 5.) This rests upon the top of the bottle and holds the lock until the upper end thereof is bent over in putting on the cap.

'It will be seen that the cap can only be re- IOO moved after breaking in or cutting laway responds to the mark 17 on the bottle, and unless the two marks agree the purchaser will readily see that the bottle and its contents have been tampered with.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the neck of the bottle, of a cap to thread thereon, and a loek provided within the cap between the side thereof and the side of the neck, and means whereby said lock is held stationary during the act of turning on the cap, substantially as described.

2. The combination with the neck of the bottle, of the cap to thread thereon, said neck and said cap being threaded, and a lock or splinter arranged within the cap and between the sides thereof and the neck, and adapted to prevent the unscrewing of the cap, and means whereby said lock is held stationary during the act of turning on the cap, substantially, as described.

S. The combination, with the neck of the bottle of the cap to thread thereon, said cap and neck being threaded, a gap being provided in said thread on one of said parts and a recess provided in the other part, and a lock or splinter arranged between the neck and the sides of the cap in said gap and said recess, whereby the unscrewing of the cap is prevented.

4. The combination, with the neck of the i bottle, of a cap to thread thereon, said cap l provided with a fragile or weak top, the bottle and said cap bearing the same or similar marks, means for locking said cap upon the neck of the bottle, said means'adapted to prevent the removal of the cap until the weak portion thereof is destroyed,and means whereby the locking device is held stationary during the act of turning on the cap, substantially as described.

5. The combination, with the bottle, having a neck provided with a thread, with the cap having a thin fragile top, an interior thread and a recess 1l in its side, the thread upon the neck being provided with a gap 5, and the lock or splinter arranged in said gap and having a part to lock in the recess in the cap, the upper end of said lock or splinter being bent down within the cap when the same is screwed in place, substantially as described.

6. The combination, with the neck of the bottle provided with the thread 4, having the gap of the cap provided with the internal thread lO and the recess l1, and the lock or splinter G, having the tongue l2 to engage in said recess l1, the lower end of said splinter resting upon the lower end of the thread 4, substantially as described.

In testimony whereof I have hereunto set my hand this 5th day of August, A. D. 1896.
